Managing complex form via modal

[cubecleveland]

Hello,

We have the following flow.
A FieldArray form that can be added and removed items .

Each item is being added via modal with ADD or cancel buttons.
Id like to 'push' the new values to the formik form ONLY if the pass validation .
Im having issues tryin to 'validate' the modal inputs without actually adding them to formik values.

Any help would be appreciated.
